MATHIAS RYER VANDERKLOOT, OF CHICAGO, ILLINOIS, ASSIGNOR TO VANDERKLOOT STEEL PILING COMPANY, OF CHICAGO, ILLINOIS,

A CORPORATION OF ILLINOIS.

PILING- SPECIFICATION forming part of Letters Patent No. 786,329, dated April 4, 1905.

Application filed September 10, 1904. Serial No. 224,053.

To all whom it may concern.-

Be it known that I, MATHIAs RYER VAN- DERKLOOT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Piling, of which the following is aspeciiication.

This invention relates to piling, and more particularly to that class known as sheet-piling, used in engineering for temporary and permanent purposes, such as protecting earth excavations, for the walls of Coffer-dams, for the retaining-walls of wharves and piers,

and also for walls of buildings, oil and watertanks, and the like.

The object of my invention is to provide an improved form of metal sheet-piling consisting of a single sheet having a central body portion approximately twice the thickness of its side portions.

Furthermore, the object of my invention is to provide a piling having interlocking flanges projecting from each side of the piling in opposite directions and by which the pile is interlocked to the adjacent pile of the series.

Finally, the object of my invention is to produce a piling ofiering the least possible resistance when being driven home and in which the use of rivets or bolts as a connecting medium is not required to hold the piling together.

With the foregoing and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and described.

In describing the invention in detail reference will be had to the accompanying drawings, forming part of this specification, wherein like characters denote corresponding parts in the several views, and in which Figure 1 is an end view, partly-in section, of a series of piles embodying my invention. Fig. 2 is an end or top View showing the arrangement for a corner, and Fig. 3 is a perspective view representing a fragment of two piles joined.

In the drawings, 1 indicates the central or body portion of the pile, which is approximately twice the thickness of extensions 2 2, formed integral therewith. The side extensions 2 2 terminate in straight Wings, ribs, or flanges 3 3, formed at right angles to the reduced portion and extending laterally in opposite directions.

Projecting laterally from each side of the main body portion of the piling and at a point where the reduced extensions begin I form wings, ribs, or flanges 4 4, which are provided with hook-shaped end 5, forming a channel or groove 6, adapted to engage the rounded edge 7 of the wing 3 of the adjacentpile.

Each pile, it will be seen, presents at each side a straight wing extending in opposite direction, and intermediate the straight wings and forming an abutting angle for the straight wing of the adjacent piling I provide wings or ribs having the hooked-shaped end and by which the series of piles are locked together against any but a sliding movement upon each other. In order that water may pass through the joint thus formed, it must pass within the channel 6, formed by the hook-shaped end 5, thence between the reduced end portions of the piling to the point where it strikes the abutting angle of the wing or rib 4 on the opposite side of the pile, thence again through the channel 6. It is evident that the circuitous path the water must travel, and the sediment and solid matter which evidently will be forced into the channel during the operation of driving, and the numerous obstacles interposed to a direct flow, will tend to readily gather and hold solids and sediments which quickly seal the joint substantially watertight.

In Fig. 2 I have illustrated a method of forming the corner-piles for rectangular .or angular structures, which consists of cutting the reduced extensions ofl' of two piles at the angle formed by the wings 4 4, thence abutting said wings at 4 4. An angle is thus formed by the wings 4 4 with the bent ends forming the channel 6 6 toward each other, and in this angle a brace 8 is inserted with the edges of its two wings engaging the channels 6 6, and by means of bolts 9 the angular brace is secured to the wings 4 4, thus forming a strong corner-joint.

The method of joining the piles in series will be readily understood from the foregoing description. One of the piles being driven, the wing 3 of the adjacent pile is inserted in the channel 6 of the pile that has been driven home and the Wing of flange 3 of the pile driven home is inserted in the channel 6 of the adjacent pile, and during the operation of driving the pile being driven is held in its proper position and the flanges follow the channel, and thus form a substantially Water-tight joint the entire length of the piling.

The construction, operation, and advantages will, it is thought, be understood from the foregoing description, it being noted that various changes may be made in the proportions and details of construction Without departing from the scope of the invention.

Having fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. A piling consisting of a single member having a thick central portion and reduced extensions terminating in straight flanges, hooked flanges projecting from the body portion in opposite directions as and for the purpose set forth.

2. A pile consisting of a single metal sheet having reduced extensions terminating in straight flanges bent at right angle to the extension and a pair of hooked flanges projecting from each side of the metal sheet in different directions, said flanges interlocking with flanges on the adjacent pile substantially as described. 4

3. A section or unit for sheet-piling consisting of a pile having a thick body portion, reduced extensions formed integral therewith and terminating in straight flanges bent at right angle to the reduced extension, a pair of hook-shaped flanges projecting from the body portion in opposite directions and forming abutting angles for the straight flange carried by the adjacent pile.

4. A series of interlocking piles having a thick central body portion, reduced extensions formed integral with the body portion and terminating in straight flanges bent at right angle to the reduced extension and extending in opposite directions, flanges projecting from the central body portion at a point Where the reduced extension begins, and terminating in hook-shaped ends forming a channel for interlocking with the straight flange on the adjacent pile as and for the purpose described. In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
